I’d say Tekken has much more legacy than SNK’s stuff. I’m not trying to downplay the SNK games, but Tekken is HUGE. It’s the third best selling fighting game series behind Smash & Mortal Kombat, that’s not even including the money its made in arcades.
I know they’ve all had Nintendo appearances, but they’re still all faaaar more associated with PlayStation. You can’t even buy a Metal Gear or Tekken game on Switch as of now.
I also don’t see why he wouldn’t fit outside of being Xbox man, which really shouldn’t be a problem given all of the PS centric characters we’ve been getting.
The only gritty Halo games are Reach & 4. The rest of the series has a fun, pulpy tone to it; there’s a lot of
levity in those games. I’d say Fire Emblem & Metroid are more serious/dark tbh.
